Complete Dark Mode Implementation Summary

Overview

We have successfully implemented a comprehensive dark mode functionality for your Flutter LBA app. Every screen, component, and widget now properly supports both light and dark themes with complete color adaptation.

What Was Implemented

1. Color System Restructure

• File: lib/res/colors.dart
• Changes:
  • Created separate LightAppColors and DarkAppColors classes
  • Added dynamic AppColors class that switches between light/dark colors
  • Added new color properties for better theme support
  • All colors now have proper dark mode equivalents

2. Theme Management

• File: lib/utils/theme_manager.dart (NEW)
• Features:
  • Centralized theme management using Provider pattern
  • Automatic theme persistence using SharedPreferences
  • Complete MaterialApp theme definitions for both light and dark modes
  • Seamless theme switching without app restart

3. Persistent Storage

• File: lib/utils/sharedPreferencesKey.dart
• Changes: Added isDarkMode key for storing user theme preference

4. Main App Integration

• File: lib/main.dart

• Planner: lib/screens/mains/planner/planner.dart - All chat bubbles, suggestions, and UI elements
• Notification Settings: lib/screens/mains/profile/notification_settings_page.dart - All switches and options
• QR Scanner: lib/screens/qr_scanner/qr_scanner_page.dart - Scanner overlay borders

6. Widget Component Updates

• CustomCard: lib/widgets/customCard.dart - Background and text colors

7. Dependencies

• File: pubspec.yaml

Resolution Summary

The initial issue was that only some parts of the app supported dark mode while critical screens like navigation and planner remained in light mode. We have now:

Future Enhancements

Consider these potential improvements:
